SOLE-CHA'NNELING MACHINE.

SPECIFICATION forming part of Letters Patent No. 607,990, dated July 26, 1898.

Application filed March 19, 1895. Serial No. 542,421. (No model.)

To all whom it may concern.-

Be it known that I, FRANCIS J OSEPH FREESE, of Lowell, county of Middlesex', State of Massachusetts, temporarily residing in the city of Montreal, in the district of Montreal and Province of Quebec, Canada, have invented certain new and useful Improvements in Sole- Ohanneling Machines; and I do hereby declare that the following is a full, clear, and exact description of the same.

This invention relates to sole-channeling machines, and more particularly to machines for cutting the surface and edge channels of insoles, the object being to provide a powerdriven machine for this purpose embodying as novel features various combinations of parts and the particular construction of several of the devices used therein, as hereinafter described, and particularly pointed out in the claims.

For full comprehension, however, of the invention reference must be had to the annexed drawings, forminga part of this specification, in which like symbols indicate corresponding parts, and wherein Figures 1 and 2 are respectively side and front elevations of the machine, part of the supporting-pedestalbeingbroken away; Fig. 3, a detail transverse horizontal section .of the fore part of the machine, taken on line 3 3, Fig. 2; Fig. 4, a detail side elevation, partly in section, of a portion of one of the work-guides with a Whetstone mounted thereon; Fig. 5 being a detail horizontal sectional view showing the position of the edge workguide relatively to the rotary cutter.

The machine now to be described has in common with other sole-channelers a stationary surface-channeling knife or cutter a, adjustable, as usual, in a groove a in a carrierblock a and clamped in position by a plate 01 secured by set-screws a to such blocks, the latter being carried, preferably, by a removable bracket-piece b, (with which it has a tongue-and-groove connectiom) bolted at b to the frame of the machine, and through which bracket a screw-stud bipasses to retain such carrier-block in place. The edgechanneling knife or cutter in this case is in the form. of a horizontally-rotating disk a, mounted rigidly on the lower end of a vertical spindle c, which for purposes of adjustment is preferably carried within asleeve c screw threaded on its exterior to take either into a screw-threaded vertical aperture through the frame of the machineor into a second encircling sleeve to be presently mentioned, the upper end of the spindle c carrying drivingpulleys c rigidly mounted thereon, and the sleeve 0 having a finger-nut c fixed upon its upper end.

In order that an equal feeding of the stock against theresistance of both knives or cut ters may be secured and also that the feed may act as a stay to the stock in the event of one cutter being dispensed with at any time, the feed-diskdis located to rotate in a vertical plane in advance of each cutter and centrally between the respective edges of both and a short distance above same when they are in their normal working position, as shown in Fig. 1, the feed-disk being rigidly mounted.

on a horizontal stub-axle d, bearing in the frame of the machine.

The feed-disk has two laterally-projecting concentric side faces, one of which, 01 is toothed to intermesh with and allow the disk to be driven bya pinion 6, carried by a shaft d having its forward end bearing in the bracket-piece b and its rear end, which carries a gear-wheel 6, bearing in the frame of the machine. The other laterally-project ing side face d of the feed-disk is plain and serves as a gage to restrict the depth to which the friction-teeth of the feed-disk d will sink into the work.

To insure the feeding of the work in a true horizontal line, I attach a vertically-adjustable gage or guide in the form of abent fingero to the side of the frame by screws 0'1), taking through slot 11 in the upper end of such bent finger or guide into the frame of the machine, and such adjustable gage is located so that its lower bent portion will bear upon the work in close proximity to the feeddisk.

Beneath the cutters and feed-disk. is arranged a table or work-support, preferably in the form of a disk f, with the periphery of its upper surface beveled, as at f, and rigidly mounted. on the upper end of a rotating shaft f carried slightly out of the vertical in bearings f f projecting from the frame, the body of the table being consequently slightly out of the horizontal, but with its beveled portion f presenting a horizontal surface to receive the work, which construction and arrangement while securing the large rotating surface yet leave a convenient space between the table and the outer edge of the stock for handling the stock. A

To secure the rotation of the table or worksupport, a bevel-gear f is mounted upon the shaft f, has a feather-and-spline connection therewith, and intermeshes with a bevel-gear g, carried rigidly on the front end of a horizontal shaft g, which bears in the frame of the machine and carries on its rear end a gearwheel 9 similar to the one e. These gearwheels e and g are of the same size, so as to rotate the shafts d and g, upon which they are mounted, at the same rate of speed, and they are operated (through the driving-pulley G) by an intermediate gear-wheel H, in mesh with both, carried upon and rigidly connected to a sleeve H, mounted loosely on a stud-axle H carried rigidly on the rear of the frame of the machine.

The connection of bevel-gear f to shaft f by feather and spline allows of avertical adjustment of the table to and from the cutters a and 0, so that various thicknesses of stock can be operated upon and the stock set in place.

The table is kept normally elevated to a position in close proximity to the cutters by means of a coiled spring 1, encircling the shaft f and bearing between the upper side of bevel-gear f and the under side of a collarf", mounted rigidly on such shaft f and as a means for lowering the table from the cutters I connect the lower end of the vertical shaftf to a treadle F by a swiveling connection f It is not essential that special means be provided to rotate the work-support,as it may be mounted to rotate in its bearings and follow and support the stock by friction alone when it is fed by feed-disk d.

To enable the edge-channeler c to be adjusted to cut at various angles, I mount its carrying-sleeve c in a second sleeve 70, screwthreaded on its inside to receive it, and this sleeve is pivotally supported in an opening 70 in the frame of the machine by set-screws k 70 taking in the frame and located so as to bear on opposite sides of such sleeve 76. A coiled spring 70 is carried in a recess k in the rear side of opening 70 and adjusted to bear upon the upper end of sleeve 70, so as to keep it normally in contact with a set-screw 70, carried in the front portion of the frame and projecting into the opening 70, by means of which set-screw 7c bearing upon sleeve 70 the the cutter c is horizontally adjusted. The vertical adjustment of this cutter 0 can be secured either by rotating sleeve 0 in sleeve is by means of finger-nut c or by loosening the set-screws k 70 and raising or lowering the sleeve 76 until the cutter c is brought to the desired position.

The adjustable guide that I prefer to use in connection with cutter c to regulate the depth it is to cut into the work is in the form of an arm m, pivotally connected to the vertical arm of a bell-crank lever n, fulcrumed at n to a carrying-plate 0, secured to the side of the frame of the machine by screws 0 0 and screw-bolt 0 having a perforated head. The horizontal arm of this bell-crank lever n is connected by a rod 19 with a treadle p, and such horizontal arm is kept normally elevated by the action of a V-shaped spring q, having one end bearing in the perforation in the head of screw-bolt 0 and its other end bearing behind a shoulder m on arm m, so as to exert a forward and downward pressure upon such arm m.

The movement of the bell-crank lever is regulated by means of adjustable stops, preferably in the form of screws 4 0", taking, respectively, into interiorly-screw threaded sleeves 0" r carried by the plate 0.

If desired, a second guide similar to the one m and in the form of a bar 3, also pivotally connected at the rear end to the vertical arm of the bell-crank lever 01 and extending forward to bear against the edge of the stock beneath the cutter, can be used to guard against any possibility of a thin upper half of the stock being so crumpled as to allow of misplacement of the sole, the guide 3 preferably having a depression 4 to clear the retaining-screw of the cutter and being thrown forward by a similar V-spring 5.

Either of the guides on or 3 may, if desired, carry a Whetstone 6, shown in this instance as carried by guide 3 for permanently acting IIO of the grinder-disk s will project a short distance over the periphery of the edge-channeler 0 when in its working position. A rotary motion is imparted to this grinder through a pulley 3 mounted rigidly upon the upper end of its vertical spindle s from pulley-block 0 with which it is connected by a belt 8 The pulley-block c is operated by pulley-and-belt connections 25 t with any available initial power.

The upper edge of sleeve 0 that carries the edge-channeler, is preferably graduated, and the finger projections o of finger-nut c register with such graduations, thus providing a means whereby the vertical adjustment of cutter 0 can be regulated with exactness.

To sharpen the edge channeler or cutter c, it is raised until it comes into contact with the grinder-disk 3, this, of course, being done while both cutter and grinder-disk are rotating.

To cut a surface and an edge channel in an insole on a machine constructed according to my invention, the table or work-support must first be lowered and the work set in place,witl1 its edge to be operated upon bearing against the work-guide m and ready to be gripped by the feed-disk cl and the table, which happens immediately the table is raised.

The depth of .the edge channel can be varied by moving backward or forward the workguides 'm 3 by depressing or releasing the treadle 9, thereby allowing the cutter to enter the work a greater or less degree, as is required, for instance, in channeling an insole where the shank requires a greater depth of channel than the fore part, the stops 4 r being made adjustable, so that the extremes of depth of the edge channel can be regulated.
